Heat Balance and Its Effect on Building Types

Abstract

The performance of direct heat gain system is affective by the sever summer heat environment in the building design types in Iraq. Therefore, it is important to consider the outdoor understand the trends of local buildings (modern and traditional intensive buildings type) climate environment while designing direct heat gain system. Base on analyzing the long term weather data over the past 10 years and examine the practical issues of building design, useful climatic information and patterns are identified. The provided information will enable people to better and to build up the resources for assessing important issues of renewable energy and environmental design and to determine indoor environmental quality based on the outdoor microclimate. The simulation result reveals how the relationship between the outdoor environment and indoor factors (indoor design building) the performance of direct heat gain system. The results indicated that the thermal storage mass of direct of direct heat gain system raises the room air temperature due to the large area of window. The climatic data currently being used for energy design calculations leads to inaccuracies in predictions of energy use. Heating coefficients were consistently positive and their values varied between 0.1, to 0.46, while albedo values varied between 0.19 and 0.37. The results indicated that there is little monthly variation in the values of nocturnal net radiation. The energy cost of cooling fuel estimated for both building types.
